Let me give you my favorite number that I rarely call : 1-800-222-1222
It's the poison control hotline.
They know what's an overdose and what's not. What to flush with water, vinegar, or milk. When to induce vomiting, when NEVER to. When to run to the ER, when to handle it at home. If it's chemical in any way (liquid, powder, crystal, ointment, or insect) they've got it on file and exactly what to do and in what measure.
Fortunately baby stuff is liberally tested and pretty much safe...because lets face it...if it's designed for baby use it will eventually end up in every orifice, on the carpet, coating our skin, & smeared in our hair. We'll end up breathing it in, pouring it on ourselves, and accidentally eating it. And that's US. Our little ones usually beat us to it, but eventually, we'll dose ourselves with every conceivable Johnson&Johnson product known to man. After all...We're running sleep deprived with little agents of entropy kicking their feet or cannonball heading us when we're least expecting it.
You did good.
